SPECIFICATION forming part of Letters Patent No. 472,832, dated April12, 1892.

Application tiled May 29, 1891. Serial No.394,601. (No model.)

T0 all whom t may concern.-

Be it known that I, HUGH M. SWEENEY, a citizen of the United States, anda resident of Boston, in the countyof Suffolk and State of-Massachusetts, have invented new and use- &c., although it may toadvantage be used on other window-shades, as will hereinafter be morefully shown and described, reference being had to the accompanyingdrawings, wherein- Figure l represents a front elevation of vawindow-curtain provided with my invention. Fig. 2 represents across-section on the line X X in Fig. l, shown as enlarged. Fig. 3represcnts a vertical section of a modication of the invention, and Fig.4 represents a crosssection on the lineYY shownin Fig. 3. Fig. ,5represents a vertical section of another modification, and Fig. 6represents a crosssection on the line Z Z shown in Fig. 5.

Similar letters refer to similar parts wherever they occur on thedifferent parts of the drawings. l

The object of my invention is to provide a window-curtain with afriction device for retaining it in any desired position, so as toprevent it from flying up in case a spring-fixture is used and toprevent it from sagging down if used in connection with otherkinds ofcurtain-rollers or curtain-holding devices.

vIn Fig. l, A represents a curtain-roller of any well-knownconstruction, such as a springfixture or otheikind, as may be desired.

B is the shade or curtain, as usual, having a bar b attached to itslower portion.

C C are the vertical guide-posts,which may be made of wood with iiatinner surfaces, as shown in Figs. 1 and 2,-or may be made as metal rodsor tubes, as shown in Figs. 3, 4, 5, and 6. To each end of the rod b isdetachably secured by screws a metallic box or chambered plate D,containing a spring pressed friction-block D', which is guided andsupported by the side walls of the box and held with a yielding pressureagainst the post or rod C by means of a spring D, preferably interposedbetween said box and frictionblock, as shown. To the upper and lowerends of the boxes D D are journaled the antifriction guide-rollers E E,that serve for the purpose of preventing the bar b and itsfriction-blocks from kinking or binding against the posts or rods C C incase the said bar b 6o should be raised or lowered while in an inclinedposition, said rollers thus serving to properly guide the curtain whileit is being. operated. The boxes D and their frictionblocks D may beguided relative to the posts or rods C in any suitable manner, andl haveshown for this purpose in Figs. l and 2 vertical rabbeted side pieces CC. In Figs. 3 and 4 the friction-blocks are shown concave,

so as to it the rods C, and in Figs. 5 and 6 7oV the said blocks arelikewise shown concave, and additional outside rollers E E are shown formore effectually guiding the boxes -D D on the rods or tubes C C. Bydetachably securing the curtain rod or bar Z9 to the metal- 75 lic boxesD it is possible to remove the curtain and its rod or bar while leavingthe boxes in position on the guide-posts C, so that the boxes,

with their friction-blocks, will always be in' correct position on Ytheguide-posts, even 8c though the curtain and its rod or bar b areremoved.

Either of the above-mentioned guide devices maybe used to equaladvantage without departing from the essence of my invention. 8 5

Having thus fully described the nature, construction, and operation ofmy invention, I wish to secure by Letters Patent and.claiml. Thecombination, with a shade -roller,

vertical guide-posts, and a shade having a 9c shade-bar at its loweredge, of a box secured to each end of the shade-bar and provided withanti-friction rollers bearing against the guide-posts, a friction-blocklocated inside of each box and guided by the side walls thereof, 9 5

and a spring acting toY press each frictionblockv against a guide-post,substantially as described. l

2. The combination, with a shade-roller,

vertical guide-posts, and a shade having a roo.

shade-bar at its lower edge, of a metallic box secured to each end ofthe shade-bar and guided in engagement with the guide-posts, afriction-block located inside of each box and box, and a springinterposed between each 'box and its friotion-blockcto press the latterI 5 against a guide-post, substantially as described.

In testimony whereof I have signed my name to this specification', inthe presence of two subscribing witnesses, `on this 28th day 2o of May,A. D. 1891.

HUGH M. SWEENEY.
